Boulder vs Turku

Informations

In geology, a boulder is a rock fragment with size greater than 256 millimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks (American English) or stones (In British English a rock is larger than a boulder). The word boulder is short for boulder stone, from Middle English bulderston or Swedish bullersten.In places covered by ice sheets during Ice Ages, such as Scandinavia, northern North America, and Siberia, glacial erratics are common. Erratics are boulders picked up by ice sheets during their advance, and deposited when they melt.

They are called "erratic" because they typically are of a different rock type than the bedrock on which they are deposited. One of them is used as the pedestal of the Bronze Horseman in Saint Petersburg, Russia. Some noted rock formations involve giant boulders exposed by erosion, such as the Devil's Marbles in Australia's Northern Territory, the Horeke basalts in New Zealand, where an entire valley contains only boulders, and The Baths on the island of Virgin Gorda in the British Virgin Islands. Boulder-sized clasts are found in some sedimentary rocks, such as coarse conglomerate and boulder clay. The climbing of large boulders is called bouldering.

Turku ( TOOR-koo; Finnish: [ˈturku] (listen); Swedish: Åbo [ˈǒːbʊ] (listen), Finland Swedish: [ˈoːbu] (listen); Latin: Aboa; Russian: Турку, formerly Або) is a city and former capital on the southwest coast of Finland at the mouth of the Aura River, in the region of Finland Proper (Varsinais-Suomi) and the former Turku and Pori Province (Turun ja Porin lääni; 1634–1997). The region was originally called Suomi (Finland), which later became the name for the whole country. As of 30 September 2018, the population of Turku was 191,499 making it the sixth largest city in Finland after Helsinki, Espoo, Tampere, Vantaa and Oulu. There were 330,192 inhabitants living in the Turku sub-region, ranking it as the third largest urban area in Finland after the Greater Helsinki area and Tampere sub-region. The city is officially bilingual as 5.2 percent of its population identify Swedish as a mother-tongue.It is unknown when Turku gained city rights. The Pope first mentioned the town Aboa in his Bulla in 1229 and the year is now used as the foundation year of Turku. Turku is the oldest city in Finland, and served as the most important city of the eastern part of the Kingdom of Sweden (modern-day Finland). After the Finnish war, Finland became an autonomous grand duchy of the Russian Empire in 1809. Turku lost its status as capital of the Grand Duchy in 1812, when Tsar Alexander I of Russia decided to move the capital to Helsinki.

It was only after the last great fire in 1827 that most governmental institutions were moved to Helsinki along with the Royal Academy of Turku (Turun Akatemia) founded in 1640, which then became the University of Helsinki. Turku continued to be the most populous city in Finland until the end of the 1840s, and it remains the regional capital and an important business and cultural center and port. Because of its long history, it has been the site of many important events, and has extensively influenced Finnish history. The history of the country is closely linked to Turku, the former capital. Along with Tallinn, the capital city of Estonia, Turku was designated the European Capital of Culture for 2011. In 1996, it was declared the official Christmas City of Finland. Also, Turku has been officially declared the "Food Capital of Finland", because it holds a number of Finland's oldest and high-qualited restaurants, including the country's top-rated Indian restaurant Delhi Darbar, and a historically famous fish market held twice a year.Due to its location, Turku is a notable commercial and passenger seaport with over three million passengers traveling through the Port of Turku each year to Stockholm and Mariehamn.
